At Spark, we’re making it easier to bring connected devices to market with the Spark Core, our Wi-Fi development kit, and the Spark Cloud, our cloud service for connected devices. And to prove it, we built our own approximation of the Nest Learning Thermostat in one day — and we’ve open sourced everything. In this process, we’ve come to respect the incredible technical challenges that Nest has solved while also coming to understand how much the game has changed since they first started.
